Active materials
A water dispersible granule formulation containing 250 g/kg rimsulfuron, a sulfonylurea, for the control of certain broad-leaved weeds in potatoes and forage maize.
- TITUS must not be applied to any crop suffering from stress as a result of drought, water-logging, low temperatures, pest or disease attack, nutrient or lime deficiency or other factors reducing crop growth.
- Due to the high level of activity of the herbicide, special care must be taken to avoid damage by drift onto plants outside the target area, or onto surface waters or ditches. Thorough cleansing of equipment is also very important - see below.
- Do not apply to po tatoes grown for certified seed.
- Before using TITUS on crops grown for processing, consult processor
- Further cultivation or ridging following application should be avoided.
- Do not apply TITUS to for age maize treated with organophosphate (OP) insecticides.
- Do not apply TITUS on for age maize undersown with grass or clover.
Weed Control
TITUS works mainly by foliar action. When tank- mixed with a suitable adjuvant or herbicide partner, it controls a range of broad-leaved weeds and gives a moderate level of control of Common Couch. It is most effective when applied to small actively growing weeds.
Susceptible weeds cease growth almost immediately after application and symptoms can be seen within about ten days. Weed control may be reduced when soil conditions are very dry.
Susceptible Weeds
The susceptibility ratings of weeds in the following tables refer to good spray cover and good growing conditions.
Weed resistance
This product contains rimsulfuron, which is an ALS inhibitor, also classified by the Herbicide Resistance Action Committee as ‘Group B’. Use only as part of a resistance management strategy that includes cultural methods of control and does not use ALS inhibitors as the sole chemical method of grass-weed control.
When herbicides with the same mode of action are used repeatedly over several years in the same field, selection of resistant biotypes can take place. These can propagate and may become dominating. A weed species is considered resistant to a herbicide if it survives a correctly applied treatment at the recommended dose. Development of resistance within a weed species can be avoided or delayed by alternating (or tank-mixing) with suitable products having a different mode of action.
TITUS can be used on all soils and is unaffected by high organic matter.
Avoid high light intensity (full sunlight) and high temperatures (above 21°C) on the day of spraying.
Avoid periods of substantial day to night temperature changes or when frost is expected. Very dry conditions may reduce the effectiveness of the product.
Volume and application
When applying TITUS, care should be taken not to overlap spray swaths.
Apply in 200 litres of water per hectare, using suitable equipment to give good spray cover. The spray quality should be MEDIUM (as defined by BCPC), applied at a pressure of 2 - 3 bar.
Following crops
Only winter wheat should be drilled in the same calendar year as a crop treated with TITUS. Only barley, wheat or maize should be sown in the spring of the year following treatment. In the second autumn following treatment, any crop may be drilled.
Before using TITUS, make sure that the spraying quipment is clean and free from contamination with other pesticides.
TITUS mixes easily with water, but the following mixing procedure should be followed: Quarter fill the spray tank with water, start the agitation and add the required quantity of TITUS directly to the tank without prior creaming. Continue agitation while topping up the tank and while spraying. Do not leave the sprayer standing without agitation with chemical in it.
- TITUS is compatible with metribuzin (M11304) on potatoes. Metribuzin mixtures should not be applied to metribuzin intolerant varieties (refer to metribuzin label).
- In any tank-mix, add TITUS to the tank first and ensure it is fully dispersed before adding the partner product. Products should only be tank- mixed if each product can be applied within the label recommendations for its use.
Do not apply TITUS in sequence or in tank-mixture with a product containing any other sulfonylurea.
- Please consult your distributor for list of approved adjuvants.
Crop safety
TITUS may cause transient chlorosis and/or crop stunting from which the crop usually recovers. TITUS must not be used on potatoes grown for seed.
TITUS must be applied in the spring pre-emergence of the crop up until the crop is 25 cm high.
Apply TITUS at 50g product/ha plus adjuvant at 0.1% v/v.
Crop safety
TITUS can be applied to the following varieties. Please contact your distributor for details on other varieties.
TITUS must be applied in the spring post- emergence up to the 4-collar stage of the forage maize.
Apply TITUS at 50g product/ha plus adjuvant at 0.1% v/v.
